The proximate analyses of the cuts were carried out to determine the percentages of total moisture, fat (ethanol extracted), nitrogen (N 6.25 = protein) and ash. The protein methodology was based on the Dumas Combustion method (Einarsson, Josefsson, & Lagerkvist, 1983). The samples were combusted at ±1100– 1350 C and 10 cm3 of the sample gas was analysed. A thermal conductivity cell detected the difference in thermal conductivity caused by the presence of nitrogen. The conversion factor of 6.25 was used in the calculation of the protein content
